The global diet diversity spectrum in avian apex predators.
Article in Proceedings. Biological sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Some predators depend heavily on one or a few prey types, and others have exceptionally broad diets. It is unclear how this diet variation arises. Here, we demonstrate a strong link between diet species richness and Shannon entropy of prey frequencies (a diet diversity spectrum) for a globally distributed group of apex predators-raptors. For many raptors, diet entropy is consistent with random sampling expectations given a lognormal distribution of abundances among prey species. Yet most species-rich diets often approach the maximum possible diet entropy, indicating an unexpected level of diet evenness that is not predicted by theory. Positioning along this diet diversity spectrum is linked to evolutionary history, the types of prey that are acceptable and the role of raptors as food web integrators through cross-habitat sampling. These results suggest that raptors may have a highly stabilizing effect on terrestrial food webs and play an important role in maintaining biodiversity.
